A heart failure data management system for assessing and treating. Further, the present invention provides IH
Based on data obtained from S, network, internet, intranet, and worldwide
The present invention relates to a system compatible with the web and a two-way communication system.

BACKGROUND OF THE INVENTION The need for frequent and continuous monitoring of vital signs associated with inpatients, particularly critically ill individuals, is an important aspect of healthcare. Almost all hospitalized patients
Periodic measurements are required for recording blood pressure, body temperature, pulse rate, etc. Such monitoring generally involves having a healthcare worker regularly visit the patient and / or using a dedicated device connected to the patient or brought into the patient room to monitor the vital signs of the patient. Observing has been done. Such monitoring techniques are not ideally cost-effective because they are very labor intensive.

A large number of implantable implants for cardiac monitoring and / or therapy in which a sensor is located in a blood vessel or ventricle and is connected to an implantable monitor or therapy delivery device. Medical device (IMD
) Is used for diagnosis and treatment. Such systems include, for example, implantable heart monitors, therapy delivery devices, and drug delivery devices. All of these systems include sensing electrodes and sense amplifiers that record and / or derive sense event signals from an intracardiac electrogram (EGM).
In current cardiac IMDs that provide therapy, the detected event signals are used by operational algorithms to control the delivery of therapy. The selected EGM signal segment,
Internal RAM for telemetry for detected events, histograms, data, etc.
Stored in and later sent to an external programmer. Use other than or in addition to medical conditions delivered by IMD-delivered treatments, either temporarily or for long periods of time in the body organs or blood vessels available for the above-mentioned IHM to monitor physiological conditions. Efforts to develop implantable physiological signal transducers and sensors are also ongoing for many years.

For a comprehensive list of implantable therapeutic devices, see US Pat. No. 5,330,505.
No. 6,058,037, and an implantable sensor for detecting a wide variety of cardiac physiological signals. This patent is incorporated herein by reference in its entirety.

In general, IHM measures signal values for blood pressure and body temperature that result from changes in cardiac output that may result from heart failure, ventricular tachycardia, flutter, or fibrillation. Such changes may also reflect changes in the body's need to supply oxygen to the blood. For example, monitoring a significant decrease in blood pressure in the ventricles (particularly the right ventricle), along with accelerated or chaotic EGMs, is sufficient to cause automatic delivery of defibrillation or cardioversion shocks. Suggested as an indicator of fibrillation or tachycardia. More recently, it has been possible to monitor changes in blood pressure by comparing the values associated with the normal contraction and relaxation of the heart with those that occur during high rates of tachycardia, flutter, or fibrillation. Proposed.

[0006] Several cardiac pacing systems and algorithms have been proposed that handle monitored mean blood pressure, ie, monitored dp / dt, and sometimes they are used clinically to treat bradycardia. ing. Such systems and algorithms detect mean or dp / dt blood pressure changes and, in response, vary the cardiac pacing rate between upper and lower pacing rates to control cardiac output. . Examples of IHM blood pressure / body temperature sensors for deriving absolute blood pressure and body temperature signals include US Pat. No. 5,368,040, US Pat. No. 5,535,752, US Pat. No. 5, assigned to the assignee of the present invention. , 564,434 and U.S. Pat. No. 4,791,931. All of these patents are incorporated herein by reference.

edtronic® Chronicle® Implantable
The Hemodynamic Monitor (IHM) is described in US Pat. No. 5,535,752 and US Pat. No. 5,564,434, assigned above, assigned to the assignee of the present invention. Absolute blood pressure values are recorded at several intervals using the disclosed leads and circuitry. The recorded data is a downlink telemetry transmission from the programmer's radio frequency (RF) head and an uplink telemetry transmission from the IHM during a telemetry session initiated by receipt of the integrated command by the IHM. It is sent to the programmer under the supervision of the doctor. Therefore, US Pat. No. 6,024,704 and US Pat. No. 6,152
No. 885, discloses a method of using an IHM to obtain a reference blood pressure signal value and an absolute blood pressure signal value with an implantable physiological sensor that detects relative cardiac blood pressure signal values for storage and transmission. There is.

Further, US Pat. No. 6,024,704 and US Pat. No. 6,152,885 disclose a reference blood pressure and / or body temperature sensor as opposed to an external calibrated atmospheric and / or body temperature sensor. It may also achieve calibration. Further, US Patent No. 6
, 155, 267 (incorporated herein by reference), this system is used to obtain digital signal values related to the diastolic pressure of the pulmonary artery and from the right ventricle. It may also combine primary cardiac blood pressure signal values.

Heart failure is a progressive disease. Treatment slows the progression of the disease, but current technology does not cure it. The optimal therapeutic regimen available to date is a combination of continuous diagnosis and drug treatment. Once a patient with heart failure is hospitalized, current technology does not provide a continuous means of monitoring the patient while he is in the hospital. The current practice is based on a dedicated programmer used to obtain the blood pressure waveform. Only trained physicians can currently uplink this data. This data is only available in the presence of such skilled physicians and therefore cannot be constantly available.

The present invention allows for continuous remote monitoring of a patient. In sharp contrast to this, previous management of heart failure would measure some variables on an outpatient basis using accurate catheterization blood pressure, which is only occasionally available. This is because it is difficult to obtain such blood pressure.

Therefore, it is necessary to make reliable and continuous measurements over a long period of time.
In addition, emerging trends in healthcare, including remote patient management systems, enable real-time communication and data exchange between the IHM in the patient's body and remote centers with physicians and other specialists. , IMD / IHM needs to be compatible with communication systems, including the Internet, World Wide Web, and similar systems. SUMMARY OF THE INVENTION The present invention relates to long-term data management for cardiac systems. In particular,
The present invention relates to IHMs for monitoring heart failure. In a more broad aspect, the present invention relates to patient management that enables the collection of long-term data for remote patient management, including remote delivery of clinical diagnostics and treatments.

Yet another aspect of the invention includes a user-friendly, screen-displayable data management system that presents clinically relevant measurements. Another aspect of the invention is in a manner that allows remote and efficient and reliable assessment of a patient's condition,
A software system is provided that allows the IHM collection data presented to the clinician to be transformed and converted.

The present invention further provides a “Method for Monitoring Implantable Medical Device and its Related System” (“Implantable Medical D
evices Monitoring and System Regarding Same ")", which is generally disclosed in co-pending application, US application Ser. No. 09 / 992,978, which is hereby incorporated by reference in its entirety. Monitoring system data organization.

The present invention provides, among other things, the availability of patient medical data in real time,
Allows the data to be transferred to one or more monitoring stations that have specialized personnel. The IHM device implemented in the present invention relates to the measurement of cardiac blood pressure, including oxygen saturation, pulmonary artery diastolic and systolic pressures, body temperature,
Other IHM devices that detect and send additional physiological signals, such as and related data, may also be utilized as transmitters or data sources. The transfer of real-time signals from the IHM to various physician portals and locations greatly enhances medical services and provides effective long-term patient monitoring.

In one aspect of the invention, an IHM device determines a patient's hemodynamic status from pulmonary and right atrial blood pressure measurements obtained from a single absolute blood pressure sensor implanted in the right ventricle. . Both of these values have been shown to correlate with the degree and extent of heart failure in the patient. The IHM constantly monitors the right ventricular blood pressure using an absolute blood pressure sensor and marks the right ventricular blood pressure at the time of a particular event.

One aspect of the present invention is to provide a means to allow a physician to view data obtained through real-time telemetry, other than using a local data retrieval system such as a programmer. Currently, physicians use this programmer to view real-time blood pressure waves along with EGM tracings. Using the present invention, the IHM device telemeters the real-time signal to the system,
From there it could be sent to a remote location via a programmer or other instrument.

Another aspect of the invention relates to presenting data from the IHM in an overview view that is useful and familiar to clinicians and patients. Yet another aspect of the present invention includes (but is not limited to) heart rate, patient activity, and blood pressure data to demonstrate that the patient is in a state of a routine data repeatable routine. (Not) data to be collected by the IHM. For example, this could be a patient lying down or a time counter, activity sensor.

Such data may be retrieved for analysis via a home monitor, programmer, or similar device, and the data may be stored and archived for analysis by a clinician or at a Medtronic server. (Records) sent over the Internet / Intranet, World Wide Web, or similar network.

This data is processed for collection with past pull-up records to form a continuous patient record. Specifically, clinically relevant measurements are drawn from this data. This would mean observing the average values measured during the daily examination, including for example the patient lying down for 5 minutes. These values and deviations or changes are compared to clinical norms and if they are abnormal, they are labeled for the user. For example, coloring and footnote markings may be used to identify or label abnormal data. Other variations such as italics, special fonts, larger fonts, email reports, fax reports, etc. may be used to identify deviations from normal clinical data or established chronological data for the patient. Good. Such clinical norms can be modified at will by the clinician on a patient-by-patient basis, in which case they serve as clinical criteria for the particular patient.

Another aspect of the invention is that, along with data from previously queried data,
The data display also includes the latest daily inspection data without limitation. The previous query date, which compares the collected value with the date ordered data, is used as the comparison value between the above two data.

Yet another aspect of the present invention is a single page view of long-term heart failure status, conversion of raw data to clinical indicators of heart failure status, analysis of index changes over a user selectable time period, Indicators and indicators to identify changes outside the clinical norm, conformance of the graphical display and data management to the patient's clinical norms, means to determine if the patient is routinely repeatable, and further data analysis And automated data analysis screening, which provides the basis for automation. Detailed Description of the Preferred Embodiments FIG. 1A depicts a patient with an implanted medical device incorporating an absolute cardiac blood pressure sensor such as the IHM discussed above.

Consistent with the structure disclosed in detail in 535,752 (incorporated above). The physiological condition monitoring IMD 100 is programmable and / or through the use of bidirectional or RF telemetry to communicate data and commands through uplink and downlink RF telemetry transmissions through the patient's skin. , An external device such as a programmer can make an inquiry.

In connection with the implantable blood pressure monitor, a series of absolute blood pressure signal values are detected in response to a signal provided by hospital personnel to initiate real-time data transmission, eg, telemetry downlink signals. Or periodically detected. The physician, clinician, nurse, or other medical professional continuously sends an absolute blood pressure value signal so that the patient's cardiac blood pressure and associated episode status recorded within the required time can be determined. The physician utilizes an external programmer to generate an inquiry command and send it to the IMD 100 via downlink telemetry transmission. The IMD 100 recognizes this command and, in response, initiates a continuous uplink telemetry transmission of absolute blood pressure data. Uplink ·
Telemetry transmission continues until the IMD system can detect no further commands.

FIG. 1B illustrates a general scheme used to send patient data to a remote clinician station. With such a communication method, the patient can be continuously monitored in a hospital environment or a home environment. The blood pressure signal is obtained from the IMD via the telemetry head 22 or equivalent device and is uplinked to the instrument 24. Instrument 24 is typical of a programmer or in-home monitor adapted to communicate with IMD 20. The instrument 24 maintains a wireless communication 27 to transfer data to the clinician's station 28. Alternatively, the instrument 24 may be adapted to transfer data via a network 30, represented by the Internet, extranets, the World Wide Web, or the like. This data is then transferred to the clinician's station via a modem, cable, or equivalent data transfer system.

The site is customized based on the research to which the user belongs and the local language used. The physician can compare his work by comparing his work data with the data compiled from other works and work guidelines. Specific comparisons and points can be provided along with custom filters. Eventually, data mining may be provided. This includes the current functionality of the CV View Extranet application and details such functionality. This portion of the site may also be customized based on the collected user data that will also be available for comparison. Further, information regarding the work of the user to obtain the comparison definition may be provided, for example, along with other practitioners in the field of expertise.

The site also contains a report that tracks the performance of the product, storing its referring physician tags. Report distribution is greatly enhanced through the features available on the web. Specifically, the content is tailored for each business. For example, product performance may be integrated with a web device, such as a palm device, which may be on the body of the patient or physician. Similarly, the accuracy of the report can be increased by combining the data. For example, a more rigorous monitoring report
It may also include more accurate battery projections obtained from actual device data tracking and continuous monitoring.

This system allows remote viewing. Specifically, the user can view the patient station remotely through an instrument connected to the Internet 30. Sessions using programmers, extenders, acute monitors, home monitors can be viewed through a web browser or PC. The user
The user has access to the switchboard of the available instruments to which they have the right to connect and obtain its content. This connection is first supported in any order, browser or instrument. Preferably, this site is customized by identifying which instruments the user has access to. Rights are transferred to physicians and clinical staff as needed.

Similarly, the link for the patient portal 52 is a secure website for patients with the Mcdtronic devices and their families already embedded. This link contains web content that requires secure access not available on the Mcdtronic public website 56. The patient portal 52 provides personalization that automatically provides only information about the patient's equipment and illness. It is combined with a consistent user interface to provide a variety of applications for a highly distributed, user-friendly web experience.

You can capture voice or text. No matter where you enter, the diary screen will provide the option to review and edit the contents of the diary. Putting a diary online makes it instantly available to all medical caregivers. Moreover, this diary does not require transcription or transfer and is part of the chart due to autofill.

Yet another significant aspect of the screen display at the patient portal 52 involves the management of patient ID cards. Requests for patient information replacement and validation are automated at the patient portal 52. The patient can also print out a replacement ID card to use while the permanent card is being processed. In addition, the patient portal 52 allows patients to manage their rights to their records. Specifically, patients will have the right to grant control and access to their records as they may find it necessary.

Referring to FIG. 5B, a quick look overview 125 of hemodynamic variables is presented. This screen provides a one week trend for the blood pressure wave of the hemodynamic variable RV. For example, triggered episodes may be selected under tachycardia, bradycardia, or patient-induced events. For example, a tachycardia-triggered event will inform the user if the patient has a tachycardia-triggered event. Similarly, bradycardia-triggered events inform the user if the patient has bradycardia-triggered events. Further, the patient-triggered event involves information indicative of the patient-triggered event.

Referring to FIG. 6, a quick look overview screen 140 represents various parameters useful in determining tachycardia or bradycardia triggers. The tachycardia trigger notification informs the user if the patient has a tachycardia-induced event. In the event of a tachycardia-induced event, a device information network, eg IHM10
0 electronically notifies the designated person, eg, a nurse, doctor, or healthcare provider, that an event has occurred by email, pager, or other means. Similarly, a bradycardia trigger notification will be dispatched if there is an event triggered by the bradycardia. The IHM 100 informs the designated person regarding the event. Notifications of patient incentives are similarly expedited.

Referring to FIG. 7, under display screen 150, the software system enables analysis of comparative values based on the comparison of previously queried values with recent values.
